From 1904-1906, Ferber collaborated with Colonel Charles Renard at Chalais-Meudon. In 1905, he built a larger glider to which he married a 12 hp motor, and on 25 May at Chalais -Meudon he launched it from an overhead cable and made a short powered glide. Although not really a successful airplane, it seems to rank as the first rationally conceived and constructed airplane to fly in Europe.
